The light is quite low in intensity. Definitely not even helpful. I consider it more decorative.
Its sensor has decent sensitivity, but it doesn't recognize day or night, resulting in it constantly turning on.
However, its adhesive tape is TRAGIC. It came off in a completely clean, unused kitchen, within 5 minutes of installation. I bought double-sided tape and everything is fine...

4 stars because while I didn't expect anything amazing, the double-sided tape ran out before we could stick it. We bought one to see how it worked and now we need another one. It's good to have them for when the little one hides from us. No power, no stories.

Very good lighting, with a good duration of about 35 seconds, sticks strongly if you clean the contact area well. The sensor is responsive. I use it with branded batteries and it works great.

Very good movie! Excellent lighting, placed inside a wardrobe, it illuminates the space satisfactorily. The motion sensor performs the best. The lights turn off in just 35 seconds after closing the wardrobe. The LED lights are densely packed, providing intense white brightness. They are enough to easily cover a large double-door wardrobe at 1m. For even larger surfaces, you can buy a second one. Each LED strip shows the points where you can cut it if it is longer than desired. I plan to buy more for different areas of the house. I am completely satisfied with this one, I wouldn't expect anything better and more efficient.
WARNING: There have been comments over time about poor adhesion to furniture. You need to be very careful when removing the blue film, otherwise the entire adhesive of the strip will be removed and it won't stick to the required surfaces.
update 19/4/22: Tremendous energy consumption. It consumes 4 batteries in just one month

Quite good for its price. The light and its response to movement are satisfactory. The only negative thing is that it turns on even with daylight, so there is a higher battery consumption and you have to turn off the sensor from the switch.

The double-sided tape did not stick.
I have put 2 in refrigerators, which the technician asked me for 100 euros each for repair - changing the lighting fixture
